6ca9825c0f Assert "adb disconnect" is called with an argument
Calling "adb disconnect" without argument would disconnect every TCP/IP
device. We must make sure scrcpy never does that.

bd3c93ae3d Remove platform-tools installation suggestion
On Windows, adb is provided in the release archive. Most missing adb
issues come from users setting the ADB environment variable to an
incorrect value (on all platforms).

Suggesting to install platform-tools to solve the problem will just make
things worse (there will be one more adb in yet another location).

Add an option --otg to run scrcpy with only physical keyboard and mouse
simulation (HID over AOA), without mirroring and without requiring adb.

c996a6d462 Fix socket close race condition
The server needs to interrupt the sockets on stop, but it must not close
them while other threads may attempt to read from or write to them.

In particular, the video_socket is read by the stream thread, and the
control_socket is written by the controller and read by receiver.

Therefore, close the socket only on sc_server_destroy(), which is called
after all other threads are joined.

Reported by TSAN on close:

17d01b5bf7 Add UI/UX support for relative mouse mode
In relative mouse mode, the mouse pointer must be "captured" from the
computer.

Toggle (disable/enable) relative mouse mode using any of the hardcoded
capture keys:
 - left-Alt
 - left-Super
 - right-Super

These capture keys do not conflict with shortcuts, since a shortcut is
always a combination of the MOD key and some other key, while the
capture key triggers an action only if it is pressed and released alone.

The relative mouse mode is also automatically enabled on any click in
the window, and automatically disabled on focus lost (it is possible to
lose focus even without the mouse).

924375487e Pass buttons state in scroll events
A scroll event might be produced when a mouse button is pressed (for
example when scrolling while selecting a text). For consistency, pass
the actual buttons state (instead of 0).

In practice, it seems that this use case does not work properly with
Android event injection, but it will work with HID mouse.

If AOA or HID keyboard may not be initialized for some reason, acksync

6102a0b5bb Move input_manager into screen
The input_manager is strongly tied to the screen, it could not work
independently of the specific screen implementation.

To implement a user-friendly HID mouse behavior, some SDL events
will need to be handled both by the screen and by the input manager. For
example, a click must typically be handled by the input_manager so that
it is forwarded to the device, but in HID mouse mode, the first click
should be handled by the screen to capture the mouse (enable relative
mouse mode).

Make the input_manager a descendant of the screen, so that the screen
decides what to do on SDL events.

Concretely, replace this structure hierarchy:

     +- struct scrcpy
        +- struct input_manager
        +- struct screen

by this one:

     +- struct scrcpy
        +- struct screen
           +- struct input_manager

2b34e1224e Use separate struct for input manager params
This avoids to directly pass the options instance (which contains more
data than strictly necessary), and limit the number of parameters for
the init function.

bc674721dc Make process_text() optional
Not all key processors support text injection (HID keyboard does not
support it).

Instead of providing a dummy op function, set it to NULL and check on
the caller side before calling it.
